Multi-Layer Silicon Nitride Laminates Exhibiting High Fracture Toughness and Crack Deflection
Abstract:
Si3N4-TiN based multi-layer ceramics laminates have been produced. With external compressive layers, laminates with a three-fold increase in KIc over the monolithic ceramics have been realised. When external tensile layers are used in conjunction with thin internal compressive layers, energy absorbing crack deflection and bifurcation processes are observed.
